VBCS Backend and Service Connections Authentication

Summary:

My question is around the Authentication method used in the "Server Identification" section when you create a new Backend/Service connection in VBCS

Content (please ensure you mask any confidential information):

Here some background: I developed a custom web app in VBCS to allow end-users perfom “Lot splits” in Oracle fusion. To achieve this I created a backend that connects to “Oracle Cloud Applications Instance” in such a way that I have access to fscm REST APIs in order to perform the needed tasks.

Everything works perfect, Lot numbers are created in Fusion as expected, but the point is that I'm using “Basic” authentication in the Backend's "Server Identification", where I manually entered user-name + credentials, let's say user_1 for illustration purposes
